Three growing boys shared a bedroom. One rolled over and, well—they needed another bedroom. The existing bedroom occupied a dormer off a large, finished attic space, which served both as an office and as a communal space for the boys and their friends. The beauty of the large space was the unbroken expanse of its cathedral ceilings.

Partition walls that are solid up to door height, and glass above create a separate bedroom for the oldest of the boys, while preserving the sense of a “great space” from the communal areas.
